GroupB Motorsport was founded on a passion for fast cars, modern and classic, and our Deeside facility boasts a full in house Dyno and rolling road facility complimented by our own machine shop and engine build department.

GroupB Motorsport found its name and identity after fully restoring the sole remaining Group B Mazda RX7 Rally car from the 1985 World Rally Championship; this prompted the name change and an exciting merger of our modern customer work with the older race and rally cars.

The company was relocated in 2014 to a larger custom built facility to enable the company to accomodate an in house restoration area and an engine build room alongside the work shop and machine shop.

Our customer work is varied and has included a 1970’s Brabham F2 restoration, Ford Escort MK1 and MK2 builds alongside more modern Subaru and Mitsubishi rally and Road car servicing.

In 2014 GroupB Motorsport were awarded the Mazda Heritage Collection contract by Mazda UK, to restore and maintain their heritage fleet. GroupB Motorsport would be delighted to quote for any preparation or service work, please call Rona or Richard for any assistance, or if you see our Team competing in races or rallies please come and have a chat.

Our facility has free Wi Fi and a customer waiting area, which we hope you will visit soon.


I bought mine (Profec B Spec II) from Silverstone Autosport. Great service and price. Package was at my door in 3days from ordering which is amazing considering I live in Malta!
